MANUFACTURE OF TILED LINOLEUM.

To all whom it may concern:

Be it known that I, OURT VON MICHA KOWSKI, director, a subject of theGerman Emperor, and resident of Bergstrasse 102, in the city of RiXdorf,near Berlin, Germany, have invented a new and useful ImprovedManufacture of Tiled Linoleum, of which the following is aspecification.

This invention relates to a process for manufacturing tiled linoleum, orsingle linoleum tiles or linoleum of the kind which imitates a tiledappearance. The manufacture of such linoleum has hitherto been effectedby stamping out single tiles from a strip of linoleum, or the tiledattern was first put together from single b ocks from which the singletiled linoleum strips or bands were cut by means of a knife or of aplane-like veneering tool. These single blocks themselves had, however,to be prepared by compressing them together from slngle linoleum plates,so that in any case it has hitherto been necessary to prepare a linoleumplate first.

According to this invention, the manufacture of rolled linoleum platesmay be entirely avoided.

It has been found that the blocks from which the tile pattern isproduced, could be produced consecutively by means of gaged rolls or bymeans of strip presses or by both of these machines. For instance, thewell known linoleum substance consisting of grains, is taken, and thesingle blocks are pressed direct from the same. If a press is used, thesaid linoleum substance is brought into the supply or feed hopper fromwhich it is seized by the transport and. kneading conveyer and forcedinto the mouth-piece of the press, so that it comes out directly in theform of a strip. By so shaping the mouthpiece the strip can at once begiven the desired cross-sectional shape. It may be square when a squarepattern is desired, or triangular, star-shaped or the like. If it isdesired to produce the said blocks by rolling, the same kind of rollsare used as in iron rolling, preferably in such manner that gaged rollsof a continually decreasing gage are In this case also a linoleum stripof suitable cross-section is obtained from which the tiles are eithercut off directly or can be combined together to form patterns, and thentiled linoleum is cut from them.

The annexed drawing explains the combination of the linoleum strips toform blocks Specification of Letters Patent.

if for instance tiles of a chess-board pattern are desired. ith one andthe same strip press strips a are made of one color and strips 1) ofanother color. These strips are cut up into single prisms of the heightD and combined to form a block as shown in the figure. The half squaresremaining at the edges can be filled in by special prisms a b oftriangular cross-section. If the linoleum strips are fresh, no specialbinding medium is required; otherwise the known binding mediumconsisting of crushed linoxid soaked in benzin is used. The singlestrips forming the block are simply dipped into the binding medium andthe whole combined to the desired pattern. Thereupon the block is cut inthe manner shown by the dotted line 0 and finished tiled linoleum is atonce obtained which if desired can be secured to a foundation.

I claim as my invention 1. The process of manufacturing tiled linoleum,which consists in forming a plurality of long strips, each substantiallyof the crosssection of the tile, in cutting these strips into sectionsof predetermined length, in assembling these separate sections withtheir major axes vertical, in compressing these sections so assembledinto a homogeneous block, and in slicing this block horizontally intosheets of tiled linoleum, substantially as described.

2. The process of manufacturing tiled linoleum, which consists informing a plurality of long strips, each substantially of thecrosssection of the tile, in. cutting these strips into sections ofpredetermined length, in treating these sections with a suitable bindingme dium, in assembling these separate sections with their major axesvertical, in compressing these sections so assembled into a homogeneousblock, and in slicing this block horizontally into sheets of tiledlinoleum, sub stantially as described.

8. The process of manufacturing tiled linoleum, which consists informing a plurality of long strips, each substantially of thecrossseetion of the tile, in cutting these strips into sections ofpredetermined. length, in assembling these separate sections with theirmajor axes vertical, in compressing these sections so assembled into ahomogeneous block, in slicing this block horizontally into sheets oftiled linoleum, and in. finally applying a suitable backing to saidsheets, substantially as described.
